Die Lösung besieht darin, daß mindestens in einem Abgasstrang ein Bypass- oder Überdruckventil angeordnet und der Abgasstrang vor der Einmündung in den Turbolader enger als die Einmündungen der anderen Abgasstränge bemessen ist. Aus diesem Abgasstrang wird infolgedessen dem Turbolader schon bei niedriger Drehzahl der Brennkraftmaschine Abgas mit hoher Geschwindigkeit zugeführt und damit wieder der Brennkraftmaschine eine ausreichende Menge Frischluft. Andererseits ist bei dieser Anordnung die enge Dimcnsionierung bei \ollast und hohen Drehzahlen nicht schädlich, da dann bereits Abgas über das Bypassventil abgeblasen wird, um in bekannter Weise ein überladen (d.h. Klingeln) des Motors zu verhindern.The solution is that a bypass or pressure relief valve is arranged at least in one exhaust line and the Exhaust tract before the confluence with the turbocharger is narrower than the confluence of the other exhaust tracts. the end As a result, exhaust gas is transferred to this exhaust line from the turbocharger even at a low speed of the internal combustion engine fed at high speed and thus back to the internal combustion engine a sufficient amount of fresh air. On the other hand, with this arrangement, the narrow dimensioning is at \ ollast and high engine speeds are not harmful, as exhaust gas is then already blown off via the bypass valve, in order to be better known Way to prevent overloading (i.e. ringing) of the motor.

Zwei Abgasstränge können in ein Sanimclrohr münden, wobei dann das Saiunielrohr an seiner Einmündung in den Turbolader enger- als die Einmündungen der anderen Saminelrohre bzw. Abgasstränge bemessen ist und die Abzweigung zum Bypass- bzw. Überdruckventil aus dem einen der Abgasstränge abgezweigt ist. Anstatt einer enger bemessenen Einmündung kann auch das zugehörige Sammelrohr bzw. der Teil des Abgasstranges hinter der Abzweigung für das Bypassventil in Strömungsrichtung enger- bemessen sein. Two exhaust lines can open into a Sanimclrohr, whereby then the Saiuniel pipe at its confluence with the turbocharger narrower than the junctions of the other Saminel pipes or exhaust lines is dimensioned and the branch to the bypass or pressure relief valve branches off from one of the exhaust lines is. Instead of a more narrowly dimensioned confluence, the associated manifold or the part of the exhaust line can also be used after the branch for the bypass valve in the direction of flow must be narrower.

Schließlich kann ein weiteres Sammelrohr an seiner Einmündung enger als die Einmündung eines dritten Abgasstranges bemessen und auch diesem Abgasstrang ein Bypass- bzw. Überdruckventil zugeordnet sein.Finally, a further collecting pipe can be dimensioned narrower at its confluence than the confluence of a third exhaust line and a bypass or pressure relief valve can also be assigned to this exhaust line.
